Line for Yesterdays Unusual Volume

[aimsicle01]

Here is the standard TOS Scan code for unusual volume.
How can I see it for yesterday? Not today.

input price = volume;
input choice = {default increased, decreased};
input percent = 100;
input length = 50;
def avg = average(price, length)[1];
def chg = 100*(price/avg -1);
plot scan;

switch (choice) {
case increased:
scan = chg >= percent;
case decreased:
scan = chg <= -percent;
}

@aimsicle01 If you are using a daily Chart you would use the following as your first line of code... We offset volume by 1 day back...

input price = volume[1];
